Dear Elation crew, I have a brand new Elation Show Designer which I want to upload some fixtures like Chauvet, Martin, ADJ by using a Null modem cable. I use this cable to upload new firmware for my Nexo amplifiers so I know this cable is working fine. But when I connect the cable (which is USB to Serial) and upload the fixtures profiles with SD Back Up tool, nothing happens on the Show Designer and the PC keeps telling it's uploading... It seems endless!!! What do I do wrong? Is this Elation board requesting different Null modem cable? Why not with USB as upload and save memory?
